Maintenance and Service
When the air conditioner is not going....
Do not overcool the room.
This is not good for the health and
wastes electricity.
Keep blinds or curtains
closed.
Do not let direct sunshine enter the
room when the air conditioner is in
operation.
Keep the room temperature
uniform.
Adjust the vertical and horizontal
airflow direction to ensure a uniform
temperature in the room.
Make sure that the doors
and windows are shut tight.
Avoid opening doors and windows
as much as possible to keep the
cool air in the room.
Clean the air filter regularly.
Blockages in the air filter reduce the
airflow and lower cooling and
dehumidifying effects. Clean at least
once every two weeks.
Ventilate the room
occasionally.
Since windows are kept closed, it is
a good idea to open them and
ventilate the room now and then.
When air conditioner is not going to be used for a long time.
